Applications: Macroporous equivalent of AG1 resin. Its effective surface area is approximately 23 m2 per dry gram, which is equivalent to 20% porosity. It can be used in organic solvents and is useful for adsorption of silica from water, separation of isozymes, and HPLC protein purification.

Separation strategy for amphoteric molecules. If the molecule is stable at a pH above its pl, an anion exchange support is used. If the molecule is stable at a pH below its pl, a cation exchange support is used.

Analytical grade (AG) resins are extensively purified to remove both organic and inorganic impurities. They are also sized to consistently give narrow wet mesh ranges, which provide high resolution and excellent reproducibility. AG resins are available as both strong and weak anion and cation exchangers and as mixed-bed ion exchangers. Many are available in several ionic forms and can be converted from one form to another. AG resins are primarily used for the separation of low molecular weight compounds such as inorganic ions, organic acids, nucleic acids, or carbohydrates.

Larger volumes and special packaging for industrial applications are available on request.
